Observation - Despite the transaction log backup every 12 hours, my LDF file keep growing. The TRN backup file size is also growing, to almost the size of the backup BAK file.This is odd because there isnt a lot of transactions to the database within a 12hours windows. The DB backup file size is about right, but I was expecting the LDF to be kept under control, and TRN files size to be much smaller.

What has not been configured correct ? Can anyone check if my Transaction Log backup script is correct ? Do I have to add more parameters, e.g WITH INIT ?
